If button folds, your 4-outer becomes a 10-outer most of the time. Not a bad deal.

This is incorrect. If button has for example A9 then your outs change from 7 to 9 and this also includes an assumption that BB doesn't have any of those outs covered.

If you had 10 outs before--you still have 10 outs--nothing changed unless button actually folded an overpair--which he wouldn't here. (unless button had 66, 77 in which case your bet has now cleaned up one or two outs) [of course I'm assuming nine high isn't actually good... but I think that's a reasonable assumption]
